PATENT OFFICE.

THOMAS B. BRIGGS, OF BROOKLYN, NEW YORK.

IMPROVEMENT IN PEN AND PENCIL CALENDARS.

Specification forming part of Letters Patent No. 133,695, dated December10, 1872.

To all whom it may concern:

Be it known that I, THOMAS B. Barees, of Brooklyn,'in the county ofKings and State of NewYork,haveinvented certainnewand usefulImprovements in Pen and Pencil Calendars; and I do hereby declare thatthe following is a full, clear, and exact description thereof, that willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawing and to theletters of reference marked thereon which form a part of thisspecification.

Figure 1 is a view, in side elevation, of a pencil embodying myprinciple or invention; Fig.2 is a view thereof, partly in section andpartly in elevation; and Figs. 3 and 4 illustrate, respectively, a sideview and a sectional one of a modification of my device.

In Fig. 1, D is a piece'of rubber, having av flange setting into theannular flange-seat E.

G is'an ordinary peucil,.which is enveloped at and a suitable distancebelow its upper end by an elongation of the said seat. This elongationhas imprinted upon it seven columns of figures indicative of the days ofthe month. A short distance from or directly below its flange the seator tubeE is diametrically contracted, within which contraction or recessis inserteda ring or band, A, bearing the letters which stand for thedays of the week, and is the part that turns.

In the modification shown in Fig. 3, the fig ured band or'tube E ismovable about the let- .tered one A, the latter being stationary,clinched over the rubber-head I) at f, passing down behind B,and turnedout at the bottom to prevent B from slipping 'off. My invention consistsof a calendar attached to a lead-pencil, &e., and is embodied in devicessubstantially as shown in the drawing.

Upon one piece I place the numbers indicating the days of the month, andupon another piece I place the letters indicating the days of the week,sothat when the first day of the month is placed in juxtaposition withthe proper day of the week, the calendar is set for the whole month.

I propose sometimes to place on another piece the months, so that thecalendar will show the month,the day, and the date but as no one is everin doubt as to the name of the month, I do not propose generally to takenotice of the months.

I propose to apply my invention to pencils, as dates are rarely requiredexcept when using a pencil.

As shown in Figs. 1 and 2, the ring or band A bearing the days of theweek maybe retained by and turn in an annular groove or recess in theband B, which bears the numbers of the days of the month and the top maybe so shaped with a bulged ring or its equivalent E, in Figs. 1 and 2,as to inclose and firmly retain a rubber head, I), or instead of arubber head a stone or other fancy head may be held.

Another form, shown in Figs. 3 and 4, may

be employed, clinching over the flanged portion of a rubber or otherhead, the letters being stationary and the figures'being upon a band, B,which turns upon A, and is prevented from slipping oft byswagingthelower end of A so as to come out flush with the surface of B.c

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

The peculiarly-constructed eraser-holder E and the tube 13, forming acalendar jointly with the eraser D and a pencil, O, or penholder,substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand.

THOMAS B. BRIGGS.
